In East L.A, nine-year-old Caine spent an entire summer building a cardboard arcade. He used boxes from his dad’s auto parts store and taped together everything he could imagine. He cleverly developed a claw game, games with hoops, and waited for the customers to come. He even made tickets and had little prizes.

Nirvan Mullick stumbled upon the Caine’s Arcade and was so impressed by what Caine had built that he decided to make a short film about it. He also organized a flashmob to visit the arcade—and if that bit of the video doesn’t make you feel warm and mushy, you might need to oil your robotic innards.
